Kiviõli Oil Shale Processing & Chemicals Plant
Deposit occurrence, oil shale mining and processing
The Baltic Oil Shale basin is located in the northwestern border of the East European Platform, continuousing from northeastern Estonia to northwestern Russia.
The area of the Baltic oil shale basin is approximatelyy 50,000 km2. The Estonian oil shale (kukersite from the locality name) is geologically related to Middle Ordovician. The richer kukersite layers are located in the lower part of Kiviõli Member of the Kukruse Stage.
The deposit locating in north-east Estonia is approximately 3000 km2, and the oil shale comprises there up to fifty laterally continuous kukersite seams having thickness from several cm to 0,9 m.
The oil shale in Kiviõli Keemiatööstuse OÜ is mined in open casts. The modern surface miner Wirtgen 2500 SM - the first one in Estonia – is used in the mine. Enterprise has an ability to mine one million tons of oil shale per year.
Chemical and mineralogical composition oil shale
The main components of oil shale are the organic matter (content ranges from 10 up to 60%), carbonate minerals (20 – 70%) and clastic minerals (15 – 60%).
The kerogen in the Estonian Ordovician kukersite has a marine origin.
Kiviõli Oil Shale Processing & Chemicals Plant
The Kiviõli Oil Shale Processing Plant, founded in 1922, represents one of the oldest enterprises in Estonia, engaged in producing oil shale products and speciality chemicals.
Nowadays the production activity of the Kiviõli Oil Shale Processing Plant develops in two directions, i.e. oil shale retorting to produce shale oil and to produce oil shale – based chemicals, whereas shale oil is notable for relatively low level of paraffinic hydrocarbons, that determine the specific routes of their processing.
The production of our enterprise reaches up to 45,000 tons S-1 shale oil, 7000 tons shale road oil and 10,000 tons road shale bitumens per year. At the same time Kiviõli Keemiatööstuse OÜ produces thermal and electric energy (110 000 MWh and 35 million kWh per year), covering the need for central heating of Kiviõli town.
